Seed Advantages in Angiosperms — NEET Biology

📚 Practice Concept
📖 NCERT Source

Seeds offer several advantages to angiosperms. Firstly, since reproductive processes such as pollination and fertilisation are independent of water, seed formation is more dependable. Also seeds have better adaptive strategies for dispersal to new habitats and help the species

Which of the above statements are NOT correct? S1: The androecium and gynoecium are classified as essential floral whorls because they directly participate in the formation of gametes and subsequent fertilisation. S2: Apomixis is a process observed exclusively in lower plants, where seeds are formed without the prior event of fertilisation. S3: Parthenocarpic fruits, typically seedless, are always the result of natural genetic mutations in certain angiosperm species. S4: While flowers are the sites of sexual reproduction, certain angiosperms can also develop seeds through asexual means like apomixis within the flower's structure. S5: The structural diversity of flowers and floral parts in angiosperms primarily reflects adaptations for ensuring efficient vegetative propagation in various habitats.
